For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.

No matter how hard you try to teach your cat general relativity, you're going to fail.

The absolute worst thing that you ever can do, in my opinion, in bringing science to the general public, is be condescending or judgmental. It is so opposite to the way science needs to be brought forth.

Black holes provide theoreticians with an important theoretical laboratory to test ideas.

A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn't age.

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.
